When developing a game, the opinion of the active part of the audience is largely taken into account.
And, as practice shows, such an emphasis on the plot often leads to a shift in the balance in one direction. Since the active part of the audience is only the tip of the iceberg.
But this is what most games suffer from, with polls on Patreon.
Regarding punishment for scenes for adult audiences: unfortunately, many authors add something to their games to artificially stretch the plot. Including a punishment system and useless mini-games (fillers).
There are no useless mini-games in the ToM, and that's great. Overall, the game tries to treat the player well, because even if the player does not make regular saves, one can play without much fear of breaking the gameplay. Is it true, some players still manage to surprise, for example, by selling plot-important items. Moreover, NPCs clearly indicate the importance of the item.
Therefore, I personally still have hope that closer to version 1.0 the game will receive branches that will save Celica from the Mary Sue syndrome (well, seriously, she already combines everything that is possible and impossible), and will also add subplots for NPCs.
The author keeps the details of the continuation of the plot secret, so for now we can only guess.
As for Steam: if it happens, it will not be earlier than version 1.0.
